LP3988IMF-3.3 Description

Short technical summary and product information.

The Texas Instruments LP3988IMF-3.3 is a 150mA micropower, ultra-low-dropout linear voltage regulator designed for portable battery-powered applications. It features a fixed 3.3V output and accepts an input voltage range from 2.5V to 6V.

 

This regulator offers a low dropout voltage of 80mV at a 150mA load and a quiescent current of less than 1µA when shut down, contributing to extended battery life. It includes essential protection features such as thermal shutdown and short-circuit current limit. The device also incorporates a Power Good (PG) flag output to indicate faulty output conditions and a logic-controlled enable pin.

 

The LP3988IMF-3.3 is designed for stability with small 1µF ceramic capacitors. It is supplied in a compact SOT-23-5 surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -40°C to +125°C.

 

Key electrical characteristics include a PSRR of 40dB at 10kHz and a fast turn-on time of 100µs. This makes the LP3988IMF-3.3 ideal for applications requiring stable power delivery in battery-operated devices.
